Larsen's Opening Trapped Piece Chess Puzzles
Larsen's Opening Trapped Piece is a tactical motif from the opening where a bishop becomes trapped after an early fianchetto or bishop sortie, most often in Larsen's Opening after 1.b3. The defining feature is that White's bishop on b2 can be shut in by a well-timed ...c5, ...e6, or a knight-and-pawn net, leaving it with no safe retreat squares.
To spot this motif, look for positions where the bishop has advanced before its supporting pawns and central squares are still under Black's control. It is especially dangerous when the bishop on b2 is hit by a pawn thrust that closes the diagonal and the queen or knight covers the escape squares, so you should calculate whether the bishop can return to c1 or a1 before committing to the line.
